So confused about Turbos. Garrett, precision, BW.

i run a BC 2.9 e85 always 9/1 comp

presicion 7675 largest rear housing

 

best turbo for Hpattern/1000Hp

makes 1000Wheel at 40psi

like i said the large was a big thing for me, but original goal of 1000hp is more important

7275 may struggle making over 1100 (maybe 1000hub)

some bearable boost at 4300 and war at 5300

off course there are factors that improve spool or lean towards power like cams, pipping size etc

thing i found most benefits in traffic is shorter diff gears, if you have a 3.2 expect it too feel 3.4 with gears AND not too mention your target boost setting is reached sooner (time not rpm)

 

with more cubes like yours i’d definitely go the largest rear housing on whatever turbo you go, and remember there’s a 9k redline so plenty of power (unlike some other motors that don’t like more than 7-7.5k) 

 

7675 sportsman is the perfect pic for 1000hp BUT “1100” maybe a 7685 if the power goal is more important than the low down power (like it is with me)

Went T4 Gen2 7685. Staying 3.2. Managed to speak to some CRD and Matouks customers who use a very similar combo to mine. 3.2/7685 some head spec variations. They say that you have to pull timing out of mid range to save bearings. Have heard (not seen) 1200hp+ hub results with my size exhaust housing. 

Speaking of, no one seems to post dynobrests any more. That was one of my favourite past times. Reading all the combos and results.

Thank you everyone for your input. It always helps.
